1 p38 Mitogen-activated protein kinase mediates IL-8 induction by the ribotoxin deoxynivalenol in human monocytes. deoxynivalenol mitogen-activated protein kinase 14 Homo sapiens
2 DON at 500 ng/ml similarly induced p38-dependent IL-8 protein and mRNA expression in PBMC cultures from healthy volunteers. deoxynivalenol mitogen-activated protein kinase 14 Homo sapiens
3 Significantly increased IL-6 and IL-1beta intracellular protein and mRNA expression was also observed in PBMC treated with DON (500 ng/ml) which were also partially p38-dependent. deoxynivalenol mitogen-activated protein kinase 14 Homo sapiens
4 Flow cytometry of PBMC revealed that DON-induced p38 phosphorylation varied among individuals relative to both threshold toxin concentrations (25-100 ng/ml) and relative increases in percentages of phospho-p38(+) cells. deoxynivalenol mitogen-activated protein kinase 14 Homo sapiens
5 Flow cytometry of PBMC revealed that DON-induced p38 phosphorylation varied among individuals relative to both threshold toxin concentrations (25-100 ng/ml) and relative increases in percentages of phospho-p38(+) cells. deoxynivalenol mitogen-activated protein kinase 14 Homo sapiens
6 DON-induced p38 activation occurred exclusively in the CD14(+) monocyte population. deoxynivalenol mitogen-activated protein kinase 14 Homo sapiens
7 Taken together, these data suggest that (1) p38 activation was required for induction of IL-8 and proinflammatory gene expression in the monocyte and (2) DON induced p38 activation in human monocytes via the ribotoxic stress response. deoxynivalenol mitogen-activated protein kinase 14 Homo sapiens
